Abstract

The large challenge of data stored in “cloud computing “is confidence and security since the sensitive data saved into data centers in cloud. These critical data may be accessed, retrieved, or edited by unauthorized person(s) or machine(s). In addition, managing, organization of sensitive data may not be secure. Therefore, the security of data is highly interesting. To increase the security of data in data centers of cloud, we have introduced scheme to ensure data security in "cloud computing" by encoding secret data using two levels of encryption are DES & RSA algorithms. And then to enhancing the security we use LSB algorithm to hide these encrypted data inside edges of color images which is called steganography. The fundamental objective of this paper is to avoid data access by opponent users. This scheme hiding encrypted secret data within images and store these encrypted secret data at the data centers of cloud and retrieves data from it when it is wanted
